Possible causes for a no-start situation that *might* be misinterpreted as a fuel shutoff problem include:
* Dead battery: The most common reason for a car not starting. Check the battery voltage.
* Bad starter: The starter motor might be failing.
* Fuel pump relay: This is a common point of failure and could prevent fuel from being delivered. You can check this relay (its location varies slightly by year – consult your owner's manual or an online forum for Mustang enthusiasts).
* Fuel pump itself: The fuel pump might have failed.
* Fuel filter: A clogged fuel filter will restrict fuel flow.
* Ignition system problems: Issues with the ignition coil, distributor (if equipped), or spark plugs can prevent the engine from starting.
* PCM (Powertrain Control Module) issues: A faulty PCM can cause various problems, including preventing fuel delivery.
Troubleshooting steps:
1. Check the obvious: Battery voltage, connections, and fuses.
2. Listen for the fuel pump: Turn the ignition key to the "on" position (don't crank the engine). You should hear a brief whirring sound from the fuel pump in the fuel tank. If you don't, it might be the pump, the relay, or a fuse.
3. Check for fuel pressure: You'll need a fuel pressure gauge to test this (it requires specialized tools and knowledge).
4. Consult a repair manual: A shop manual specific to your 1995 Mustang GT will show you the location of relays, fuses, and other components related to the fuel system.
5. Seek professional help: If you can't pinpoint the problem yourself, take your Mustang to a qualified mechanic.
In short, there's no "reset" button for a fuel shutoff switch on this car. The problem is more likely a failed component within the fuel delivery system itself.
